"""
Description:
    - This script calculates SHA-256 hashes for all Unicode characters and saves them to a file.

Functions:
    - sha256sum(string):
        Return the SHA-256 hash of a given string.
    - save_unicode_sha256(filename):
        Save SHA-256 hashes for all Unicode characters to a file.

Requirements:
    - Python 3.x

Usage:
    - Run the script to generate SHA-256 hashes for Unicode characters and save them to 'sum_uni_sha256.txt'.

Additional Notes:
    - This script may take some time to complete, depending on the speed of the system.
